9. Setting Up 

The Trex HD Monitoring is designed to work with a qualified Natus tablet computer running Natus 

Database and NeuroWorks/SleepWorks v9.3.x or later. 

 

 

 

 

9.1. Getting Started 

 

NOTE:

 In the event of a power failure, the current recording will resume using the last 

programmed settings upon the restoration of power. Bluetooth communication between the 

Trex HD Monitoring and computer, if used, will also be re-established after the Trex HD 

Monitoring is reconnected via USB.  

 

9.1.1.  Placement of the Operator and Patient 

 

Clinical Environment:

 It is expected that the operator of the system will stand or sit in front of 

the computer, but not continuously. The patient is typically lying on a bed located beside the 

system and is in no way supported by the equipment.  

 

Home (Ambulatory) Environment:

 It is expected that the operator of the system will stand or sit 

in front of the computer, but not continuously. The patient will sleep with the Trex HD Monitoring 

System and non-patient worn accessories on a bedside table, and is in no way supported by the 

equipment. 

  Trex HD Monitoring units are patient-worn.  

 

NOTE:

 There is a risk of injury if the Trex HD Monitoring unit is not properly fitted to the 

patient. 

NOTE:

 Please ensure that the patient has been provided with the proper contact information 

for assistance. 

Refer to the corresponding 

Instructions for Use

 for all system components prior to use. This should 

include, but is not limited to: cameras, computers, stimulators, and software. 

9.1.2.  Performing a standard study 

Once the equipment has been installed by your Natus qualified representative and a patient has been 

connected to the Trex HD Monitoring system, a new EEG/PSG study can be started. For details on 

beginning a new EEG/PSG study, consult the 

NeuroWorks 

or 

SleepWorks

 manual directly. 

 

WARNING: 

Do not connect more than one Trex HD Monitoring unit to the acquisition 

tablet when starting a study or at any time during an ongoing study.
